r RTQ steel boilers are high efficiency boilers with horizontal, flame reversal combustion chambers and concentrically arranged flue gas pipes. They are desi-gned for central heating and, when used in conjunction with a suitable storage cylinder, for domestic hot water production too. Because they operate at low pressure, they provide a
boilers are universally used (pressure is above 17 bar and steam generation is more than 7000 kg/hr). In these boilers, water flows inside tubes and drums, and receives heat by radiation and conduction from combustion gases flowing over the tube surface. Water- tube boilers may be classified in several ways: • Straight or bent tube.
